On clinical examination pet showed about 10-15 cm diameter of mass in the base of the left ear. No other nodular lesions were observed on the skin. The pet was active and alert with no lymph node swelling nor any clinical signs of concern. A fine needle aspiration was done to find out the aetiology of the nodular lesion.
